A new series of receivers from Vicon Industries Inc. of Hauppauge,
New York, provides variable-speed control of the company's ViStar25
series of pan-and-tilts and motorized zoom lenses. The V1305R-DC series
can be used with any NOVA (RS-422) or Vicoax II (V1422) control system,
controlling pan, tilt, zoom, and focus, as well as autoiris drive. Each
receiver works in two modes--velocity mode and preset position mode. In
velocity mode, pan and tilt can operate together at any required
combination of velocities for smooth motion at very low velocity. Up to
79 preset positions can be stored in nonvolatile memory. A preset
position defines zoom and focus as well as pan and tilt. In preset
position mode, software ensures smooth acceleration and deceleration.
Encased in a weatherproof enclosure, the receivers can also be equipped
with a 25W heater.
